Definitions

  • This invention relates to a coated article composed of a metal alloy substrate having a coating comprising a glass-ceramic selected from the barium silicate or strontium silicate system.
  • the coating over the surface of the metal substrate serves as an oxygen barrier to prevent oxygen attack of the metal at elevated temperatures and as a thermal barrier to prevent rapid heatup of the metal.
  • a common method of protecting materials from oxidation at elevated temperatures is to apply a continuous monolithic glass coating. This completely encapsulates and isolates the material from the surrounding (oxygen-containing) atmosphere. However, viscous flow of the glass coating may occur when large surface stresses develop during high temperature use. In that case, a glass barrier coating tends to develop thin spots and fail catastrophically.
  • the high temperature viscosity of the glass coatings may be increased by mixing crystalline materials with the glass frits before application of the coating.
  • these glass-crystalline mixtures sinter rather non-uniformly, the crystal size and homogeneity being very difficult to control.
  • a void-free coating with this heterogeneous glass-crystal mixture is thus difficult to obtain.
  • insulating layers of stabilized ZrO 2 are now commercially applied via a plasma-spraying technique.
  • U.S. Pat. No. 4,485,151 and No. 4,535,033 (Stecura) describe such a procedure using an alloy as a bond for the stabilized zirconia.
  • U.S. Pat. No. 4,676,994 (Demeray) describes a procedure wherein an oxidized alloy of aluminum is employed as an intermediate coating.
  • a basic purpose is to provide a reliable and reproducible oxygen barrier coating for superalloy bodies that are required to operate at temperatures above 1000° C.
  • Another purpose is to provide such a coating that is more effective, and easier to apply, than previously known coatings.
  • a further purpose is to provide an oxygen barrier coating that is non-porous, continuous and free from defects, such as pinholes and cracks.
  • a still further purpose is to provide an oxygen barrier coating that adheres tightly and resists spalling during thermal cycling.
  • Another purpose is to provide an oxygen barrier coating material that exhibits the excellent flow characteristics of a glass coating as it is fired in one temperature range, and becomes resistant to flow (due to crystallization) as it is heated in a higher temperature range.
  • a further purpose is to provide a superalloy metal body having an oxygen barrier coating that adapts the body to operating temperatures up to 1200° C.
  • a still further purpose is to provide a useful degree of thermal insulation to the metal surface.
  • the invention resides in a coated article adapted to operate at temperatures above 1000° C. in an oxygen-containing environment and comprising a metal alloy substrate, the metal alloy being selected from the group consisting of nickel-base, cobalt-base, chromium-base and iron-base alloys, and a coating forming an oxygen barrier over the metal surface, the coating comprising a glass-ceramic having a composition, on an oxide basis in weight percent, selected from a barium silicate and a strontium silicate system, the barium silicate system containing 20-65% BaO and 25-65% SiO 2 , the strontium silicate system containing 20-60% SrO and 30-70% SiO 2 , each system additionally consisting essentially of at least one oxide selected from the group consisting of up to 15% Al 2 O 3 , up to 15% ZrO 2 , up to 15% Y 2 O 3 , up to 25% MnO, up to 25% NiO, up to 30% MgO, up to 30% CoO and up to 40% iron oxide, and containing not
  • the selected oxide is Al 2 O 3 or ZrO 2 and the composition is free of R 2 O and B 2 O 3 .
  • the compositions consist essentially of SiO 2 BaO in mole ratios of 2:1 to 5:1 (approximately 40-65% SiO 2 and 30-55% BaO, both in percent by weight) and 1-10% by weight Al 2 O 3
  • preferred ranges in the strontium silicate system consist essentially of SiO 2 :SrO in mole ratios of 1.5:1 to 4:1 (approximately 45-65% SiO 2 and 30-55% SrO by weight) and 5-10 mole percent ZrO 2 or Al 2 O 3 .
  • No. 3,397,076 (Little et al.) describes fused crystallizable ground and cover coats for high temperature alloys in which the major elements are cobalt, nickel, chromium, iron or mixtures.
  • the ground coat is lithium-free and contains 35-65% SiO 2 and 12-45% BaO. Examples also contain substantial amounts of R 2 O, B 2 O 3 and/or TiO 2 .
  • No. 3,467,534 discloses glass-ceramic articles consisting essentially of 20-70% BaO and 30-80% SiO 2 and having a barium silicate principal crystal phase. A preferred example is described as considered for coating metals.
  • No. 3,531,303 (Bahat) discloses glass-ceramic articles in the alkaline earth aluminosilicate field wherein a hexagonal alkaline earth feldspar or a triclinic form is the principal crystal phase.
  • the materials are highly refractory with service temperatures up to 1700° C. and consist essentially of 12-53% SiO 2 , 17-55% RO where RO is 17-50% SrO and 20-50% BaO, 10-58% Al 2 O 3 and a nucleating agent.
  • No. 3,578,470 discloses glass-ceramic materials in the BaO-Al 2 O 3 -SiO 2 composition field nucleated with Ta 2 O 5 and/or Nb 2 O 5 that are especially suited to sealing with tungsten or molybdenum and their alloys.
  • No. 3,837,978 discloses barium aluminosilicate glass-ceramics nucleated by tin oxide, having a hexacelsian primary crystal phase, and having a coefficient of thermal expansion in the range of 50-170 ⁇ 10 -7 /° C.
  • the barrier is a coating comprising a barium silicate or strontium silicate glass-ceramic material.
  • the coating is continuous, free from defects such as pinholes, cracks, or thin spots and resists spalling during temperature cycling.
  • the invention is based, to a considerable degree, on our discovery that certain additives have an unusual effect on the crystallization properties of thermally crystallizable, barium silicate and strontium silicate glasses.
  • these additives permit the glass to soften and flow into a continuous, glassy coating before sufficient crystallization occurs to impede flow. Absent at least one of these additives, the glass tends to stiffen by crystallization before complete coverage occurs. The result is a porous, cracked coating.
  • This discovery is the key to producing an effective oxygen barrier on a superalloy surface.
  • thermal expansion coefficients of the superalloys are usually between 130 and 160 ⁇ 10 -7 /° C. This precludes many refractory glasses and ceramics from consideration. As mentioned earlier, it has also led to using a bonding layer.
  • the principal crystal phases in the glass-ceramics of the present invention are usually barium or strontium silicates. However, we have observed that there usually is a cristobalite phase present, and this may be the principal phase. Further, we have observed that there is a strong tendency for cristobalite crystals to be concentrated in a zone adjacent the interface with the superalloy surface.
  • Superalloys are well known in the metallurgical art. In general, they are highly refractory, withstanding operating temperatures in excess of 1000° C. They find application in such equipment as turbine engines, air preheaters and heat exchangers.
  • Superalloys do not have fixed composition limits. Rather, they are generally classed according to the base metal.
  • the base metals include nickel, iron, chromium and cobalt, with nickel being the most commonly used base metal.
  • the known series of nickel-base superalloys are the Nimonic, Inconel, Mastelloy, Hastelloy, Waspaloy and Rene series.
  • the cobalt superalloys include the Mar-M and AR- series.
  • the superalloys are said to be sufficiently resistant to oxidation to permit operation in an oxidizing atmosphere without a surface coating. This resistance is conferred in nickel-base alloys by chromium and/or aluminum additions. Nevertheless, under severe operating conditions, such as encountered by turbine blades for aircraft engines, even the superalloys tend to deteriorate rapidly unless protected by an oxygen barrier coating.
  • a glass-ceramic coating should retain the excellent oxygen barrier characteristics of the original glassy coating. Further, the formation of a crystalline network should stiffen the glass and render it resistant to flow once a coating is formed. Thus, the glass-ceramic coating should provide a reliable barrier to oxygen up to the temperature at which the crystal phase starts to dissolve.
  • previous studies have indicated that crystallization tends to occur too early. This precludes the degree of glass flow required to produce a continuous, glassy coating.
  • Ceramics having a high expansion coefficient commonly contain rather large quantities of alkali oxides (Li 2 O, Na 2 O, or K 2 O). These alkali ions are extremely mobile in most ceramic structures at high temperatures, and readily exchange for other ions. Therefore, they must be eliminated as major constituents in coatings that must continually operate at high temperatures. This leaves but few candidates for refractory coatings.
  • the most effective of the refractory oxide additives is Al 2 O 3 .
  • the best barium silicate coatings employ the BaO-SiO 2 binary system with an Al 2 O 3 addition of one to 10% by weight and a SiO 2 BaO mole ratio between about 2:1 and 5:1.
  • transition metal oxides as well as MgO, are effective in barium silicate glasses to provide a continuous, well-flowed glass coating prior to crystallization.
  • the transition metal oxides include MnO, NiO, CoO and FeO and/or Fe 2 O 3 .
  • Manganese oxide additions were found particularly effective in producing coatings with excellent adherence, good flow before crystallization and spall resistance. However, with substantial amounts of MnO present, the crystal phases tended to dissolve above about 1050° C., thus limiting the refractoriness of coatings containing this oxide.
  • the crystal phases formed below 1050° C. were Ba 2 MnSi 2 O 7 and cristobalite.
  • Barium silicate coatings containing FeO, CoO or NiO were not as smooth and adherent as the manganese-containing coatings. However, they were at least 100° C. more refractory. In these coatings, alpha-BaSi 2 O 5 (sanbornite) was the principal crystalline phase with small amounts of alpha-cristobalite. Small additions, generally less than 5 mole percent, of glass-forming oxides, such as ZrO 2 , Al 2 O 3 , CeO 2 , TiO 2 , Nb 2 O 5 and B 2 O 3 , improved the flow and appearance of the coatings.
  • our barium and strontium silicate coating compositions may optionally include up to about 25% by weight of other oxides. This includes 0-25% ZnO, 0-10% TiO 2 , 0-20% CaO, 0-20% SrO, 0-20% NbO 5 , and 0-10% F.
  • the alkali metal oxides Na 2 O, K 2 O and Li 2 O (R 2 O), as well as B 2 O 3 , are preferably excluded. These flux oxides tend to lower the thermal effectiveness of the coating and increase the coefficient of expansion. However, in some cases, they may be tolerated in amounts up to 5 wt. %.
  • strontium silicate coatings usually provide equally excellent adherant coatings whether fired in air or in a helium atmosphere. This renders the strontium silicate-based coatings more practical for many applications.
  • a preferred strontium silicate system contains 5 to 10 mole percent Al 2 O 3 or ZrO 2 and a SiO 2 :SrO mole ratio in the range 1.5:1 to 4:1.
  • strontium silicate base coatings are well crystallized, smooth and adherent. They may contain SrSiO 3 as a major crystal phase, with a small amount of cristobalite. However, as in the barium system, the cristobalite may be the primary phase. The cristobalite appears to concentrate at the interface of the coating and metal. As in the barium silicate system, this produces a strong bond that resists spalling when cycled, and apparently provides a good expansion match.
  • the strontium silicate compositions may contain additional oxides, beyond the modifier oxides, in amounts up to 25%. These include 0-25% ZnO, 0-20% CaO, 0-10% F, 0-10% TiO 2 , 0-20% Nb 2 O 5 and 0-20% BaO. Again R 2 O and B 2 O 3 may be tolerated in minor amounts, but are preferably excluded.
  • the surface of a preformed superalloy body may be coated with powdered glass in any conventional manner.
  • the method we prefer is electrostatic spraying, wherein electrostatically-charged, dry glass powder is very uniformly sprayed onto the superalloy body, which is supported on an oppositely charged wire mesh screen.
  • the powdered glass may be mixed with a suitable medium, e.g., water or an organic vehicle, applied uniformly over the glass surface and dried.
  • the glass powder-coated metal body is then heated to a temperature below 1000° C. This softens the glass particles and produces a dense, smooth, well-formed continuous glass coating that is essentially free from crystallization.
  • the glass-coated body is then heated to a somewhat higher temperature. This effects development of a crystal phase which forms a dense, strong, refractory, crystalline coating.
  • a key feature of this procedure is the ability to control the timing of crystallization, and thus the reproducibility of the coating process.
  • the coating has been described in terms of applying a pulverized glass over the surface of a superalloy substrate. However, it will be appreciated that fillers, and additives for other purposes, may be incorporated with the powdered glass to the extent that such additives do not prevent the pulverized glass particles from flowing into a continuous glassy coating.

  • Powdered glasses were dry pressed in the form of cylinders 1/2" in diameter. These were heat treated at temperatures of 800-1200° C. for 1/2-1 hour to determine sintering characteristics and density (non-porosity). Additionally, 4" ⁇ 1/4" ⁇ 1/4" bars were pressed and fired for determination of thermal expansion coefficient (Exp.) expressed in terms of ⁇ 10 -7 /° C.

  • Test samples were prepared by coating both sides of Inconel 718 superalloy bodies with pulverized glass as described earlier. The glass coated bodies were fired at 1100° C. for one hour in a helium atmosphere. The samples, thus prepared, were mounted on a holder and cycled 600 times. Each cycle consisted of (1) 5 minutes with a flame impinging on the samples and (2) 5 minutes cooling in air. Sample temperatures reached about 1050° C. during each cycle. Three of the four samples showed no evidence of spalling. This was an excellent result considering the severity of the thermal gradients and overall thermal shock engendered.
